With hemangiosarcoma, the pericardium fills up with blood due to rupture of the tumor. When the tumor occurs in the skin, a mass or lump can usually be felt in or under the skin. The mass may become ulcerated and bleed. When the tumor occurs in a bone, it can cause pain and discomfort.
Blood Flow Explanation. All blood goes into the right side of your heart through two main veins: The superior vena cava (SVC) and the inferior vena cava (IVC). The SVC gets blood from the upper part of the body. The IVC gets blood from the lower part of the body. Blood leaves the SVC and the IVC and enters the right atrium (RA).
